[0024] (III) Beneficial effects

[0025] 1. The rice germ is placed inside the supporting mechanism by setting structures such as a fermentation bin, a supporting mechanism, a screening mechanism, a temperature control mechanism, and a dehydration and drying mechanism. The rice germ is screened by the screening mechanism to screen out rice germs that meet the requirements. The sealing plate no longer seals the fermentation bin by continuous screening of the rice germs, so that the rice germs enter the fermentation bin. The temperature and humidity inside the fermentation bin are controlled by the setting of the temperature control mechanism, so that the rice germs ferment inside the fermentation bin and become active rice germs. After that, the active rice germs are further prepared by the setting of the dehydration and drying mechanism, thereby increasing the content of gamma-aminobutyric acid in the rice germs, improving the nutritional value of the rice germs, and avoiding the reduction in the quality of the rice germs due to the low content of nutrient components in the rice germs.

[0026] 2. The fermentation bin, the bearing mechanism, the screening mechanism and the vibration mechanism are arranged. When the rice germ is screened by the screening box, the driving motor is started, so that the cam drives the screening box to slide inside the preparation shell, so that the connecting plate is plugged into the inside of the mounting block, and the reset spring is compressed. Therefore, when the cam is separated from the screening box, the connecting plate pops out of the mounting block through the elastic force of the reset spring, so that the screening box collides with the limit block, and the screening box vibrates, thereby improving the efficiency of the screening box in screening the rice germ. The mutual cooperation between the first magnet block and the second magnet block makes the screening box more stable when in use. Through the arrangement of the screening motor, multiple screening boxes can be replaced and used alternately, thereby avoiding the problem of clogging of the screening box due to long-term use of the screening box, and facilitating the staff to clean up the unqualified rice germs screened out.

The screening mechanism includes a screening motor 5 fixedly connected to one side of the cleaning box 4. The output end of the screening motor 5 is fixedly connected to a rotating rod 6 rotatably connected to the inside of the cleaning box 4 through a bearing seat. The surface of the rotating rod 6 is provided with a vibration mechanism in a circular array. One side of the vibration mechanism is provided with a screening box 7 rotatably connected to the cleaning box 4 and the inside of the preparation shell 2. The screening motor 5 is started so that its output end drives the rotating rod 6 to rotate, thereby rotating the vibration mechanism and the screening box 7, so that the other screening box 7 and the limit block are moved. 12 are parallel, so that the screening box 7 after use is turned over, so that the unqualified rice germs in the screening box 7 are discharged into the interior of the cleaning box 4, which not only avoids the problem of clogging of the screening box 7 due to long-term use of the screening box 7, but also facilitates the collection and cleaning of unqualified rice germs by the staff. The rice germs are screened by the setting of the screening box 7. The vibration mechanism includes a mounting block 8 fixedly connected to the surface of the rotating rod 6, and the interior of the mounting block 8 is fixedly connected with a return spring 9 in a path array. One end of a plurality of return springs 9 is fixedly connected to a connecting plate 10 slidably connected to the mounting block 8. The driving motor is started 13, so that its output end drives the driving rod 14 to rotate, so that the cam 15 rotates inside the preparation shell 2, so that the cam 15 pushes the screening box 7 to slide, and drives the connecting plate 10 to slide inside the mounting block 8, so that the reset spring 9 is squeezed, and the connecting plate 10 is fixedly connected to the screening box 7. The outer side of the screening box 7 is fixedly connected with the first magnet block 11, and one side wall of the preparation shell 2 is fixedly connected with a limit block 12 corresponding to the screening box 7. When the cam 15 is separated from the screening box 7, the elastic force of the reset spring 9 makes the screening box 7 reset and hit the surface of the limit block 12, so that the screening box 7 vibrates. The efficiency of the screening box 7 in screening rice germs is improved. A second magnet block 33 corresponding to the first magnet block 11 is fixedly connected to one side of the limiting block 12. The first magnet block 11 cooperates with the second magnet block 33 to make the screening box 7 more stable when in use.

The through slot 31 corresponding to the conveyor belt 29, when the weight pushes the sealing plate 21 to rotate through the reset rod 19, causes the torsion spring 20 to twist synchronously, so that the sealing plate 21 no longer limits the connecting slot 17, so that the rice germ enters the fermentation bin 16. After the rice germ enters the fermentation bin 16, the sealing plate 21 is reset by the elastic force of the torsion spring 20, thereby preventing the rice germ from being affected by other rice germs when the rice germ is fermented in the fermentation bin 16. An electric push rod 32 is fixedly connected to one side wall of the fermentation bin 16, and a baffle corresponding to the through slot 31 is fixedly connected to the output end of the electric push rod 32. Through the arrangement of the electric push rod 32 and the baffle, a sealed space is formed inside the fermentation bin 16.

[0044] S5 Dehydration and Drying: After the fermentation of the rice germ in S3 is completed, the fermented rice germ is dehydrated and dried by a dehydration and drying mechanism. The dehydration and drying mechanism includes a drying box 25 fixedly connected to the bottom of one side of the preparation shell 2. When the fermentation is completed, the transmission motor 30 is started so that the output end thereof drives the corresponding transmission rod 28 to rotate, thereby rotating the conveyor belt 29, and driving the fermented rice germ into the drying box 25. The inner top wall of the drying box 25 is fixedly connected to an electric heating plate 26. A discharge groove 27 is provided on one side of the drying box 25. The interior of the drying box 25 is A sloping plate corresponding to the discharge slot 27 is fixedly connected, and a transmission rod 28 is rotatably connected to the inside of the fermentation bin 16 and the drying box 25 through a bearing seat. The surfaces of the two transmission rods 28 are rotatably sleeved with a conveyor belt 29 slidably connected to the drying box 25.

[0047] After the screening box 7 has been used for a long time, the screening motor 5 is started, so that its output end drives the rotating rod 6 to rotate, thereby rotating the vibration mechanism and the screening box 7, so that the other screening box 7 is parallel to the limit block 12, so that the used screening box 7 is turned over, so that the unqualified rice germs in the screening box 7 are discharged into the cleaning box 4, which not only avoids the problem of clogging of the screening box 7 due to long-term use of the screening box 7, but also facilitates the collection and cleaning of unqualified rice germs by the staff;

[0048] After the screening box 7 continues to screen the rice germ, the rice germ falls onto the sealing plate 21 through the setting of the guide plate 18. When the weight pushes the sealing plate 21 to rotate through the reset rod 19, the torsion spring 20 is synchronously twisted, so that the sealing plate 21 no longer limits the connecting groove 17, so that the rice germ enters the fermentation bin 16. After the rice germ enters the fermentation bin 16, the sealing plate 21 is reset by the elastic force of the torsion spring 20, which prevents the rice germ from being affected by other rice germs when it is fermented in the fermentation bin 16. In addition, a sealed space is formed inside the fermentation bin 16 through the setting of the electric push rod 32 and the baffle. The temperature and humidity inside the fermentation bin 16 are monitored through the mutual cooperation of the temperature sensor 22 and the humidity sensor 23. The temperature sensor 22 and the humidity sensor 23 are controlled through the setting of the controller 24, so that the fermentation bin 16 can ferment the rice germ according to the corresponding humidity and temperature, so that the rice germ becomes an active rice germ.

[0049] When the fermentation is completed, the transmission motor 30 is started so that its output end drives the corresponding transmission rod 28 to rotate, thereby causing the conveyor belt 29 to rotate, driving the fermented rice germs into the drying box 25, and the electric heating plate 26 is started to dehydrate and dry the rice germs in the drying box 25, thereby increasing the content of gamma-aminobutyric acid in the rice germs, thereby completing the preparation of gamma-aminobutyric acid-rich rice germs.
